Dacentrurus:

This gigantic European stegosaur lived at the same time as Stegosaur lived at the same time as Stegosaurus . Both dinosaurs had long spikes and plates along their backs. Dacentrurus's legs were piller-like and its thighbone was much longer than its shine bone . It was unable to outrun a theropod but it had a swing from side to side and the spikes were long enough to go right through a theropod's leg
